xgpui-gamut

Explicit linear-P3 SDR content producers; normal GPUI controls retain sRGB semantics.

EXPLORE COLOR & WIDE GAMUTAll demos →

Native Display P3 labCompare wide SDR content with ordinary sRGB controls on macOS or Windows. Run from the repository root:

cargo run --locked --config .cargo/validation.toml --manifest-path apps/xgpui-ext-lab/Cargo.toml --bin gamut-lab

Move the window to a wide-gamut display. Check Effective: WideGamutSdr and Display wide gamut: Some(true). These report negotiated support, not display calibration.

Public surface at a glance

WideColor::linear_p3 supports CustomContent; optional instanced WidePainter/WideGradient use explicit P3 shaders. Shared color math lives in xgpui-color; GPUI backends own presentation. Native color-lab compares P3 and mapped sRGB reference swatches with effective window/display status.

Boundary to investigate

Review hypothesis. No visibility changes or removal decisions have been made.

Keep profile decoding and future content producers separate from host presentation. Windows native swap-chain/display validation remains outstanding; Linux is deferred.
